MUSICAL INSTRUMENT.

Application filed 1 ments and particularly to an improved in-,

strument using tubes as the sounding members, the arrangement being such that either a striking hammer In be used for prollucing the desired sound or substantially an keyboard with an action associated therewi h.

object of the inven'cion is to provide roved construction musical instruzlo mcnt using tubes which is simple in 4;, ign

with a minimum number of parts for securing desired result.

Another object of the invention is to provide a piano action in connection with sound producin members.

object of the invention is to single member piano action. accompanying drawingis a top plan view of a musical "sclosing one embodiment oi the vention.

Figure is a sectional view through Figure 1 on line 22.

Figure 3 is a perspective view of one of the striking members or hammers of the piano action shown in Figure 1.

Figure 4 is a erspective view of a plate forming certain eatures off the invention.

Figure 5 is a perspective view showing a slightly modified construction of piano action and supporting member therefor.

Figure 6 is a perspective view of the in strument shown in Figure l, but with the auxiliary keyboard removed. Figure 7 is a perspective view of the keyboard or plate shown in Figure 6.

Referring to the accompanying drawing by numerals, 1 indicates a frame of wood or other desirable material provided with bars 2 and 3, said bars preferably diverging and accommodating sounding tubes 4. The construction and arrangement of bars 2 and 3, tubes 4 and the supports therefor are similar to the construction and arrangement shown in my (co-pending application, Serial No.

Usually this plate n ade from wood and conse quently will produce a sound or thumping action. in order to cushion or deadenthis thumping action a cushioning member is arranged adjacent each of the walls 5 and in position to be struck by the extension 16 on the rebound of the hammers 11. This cushioning member is the cord 18 extending through the groove 19 formed in the plate 5. After the striking hammers have been properly arranged and the plate 5 also properly arranged as shown in Figures 1 portiir and 2, the l is ready for us and the keys e may be used as an ordinary keyboard of a piano. if desired. these keys could Jed and the tin 'ers of the but Will not move down they are too narrow. i i hen uoper end of the projection 16 ue upper si "ace oi the plate 1 iinot one; short ii ECLVHO iOVL struci'zure, it requires a "LiQitQiG/l the sound. 1 nti modified structure i n. in t :constructhe hammer may rest ipon a bar 21 secured to the frame 1 in any desired manic-en said bar preferably a rectangular member whim is comparatively thin Where y a minimum Weight is provided and yet a maximum strength iong instruments.
